Abstract

The utility model discloses a flange bolt mounting tool, which belongs to the technical field of building tools and is technically characterized by comprising a handle and a handle, a connecting sleeve is mounted at the bottom of the handle, a connecting rod is mounted at the bottom of the handle, an upper support is mounted at the bottom of the connecting sleeve, and a lower support is mounted at the bottom of the connecting rod. The bottom end of the connecting rod sequentially penetrates through the handle, the connecting sleeve and the upper support and extends out of the bottom of the upper support. The device solves the problem that a flange bolt cannot be installed in a narrow space, the tool is easy to manufacture, convenient to construct and carry and very simple and efficient in the construction process, and an air duct upside-down installation method which is tedious and high in danger coefficient is avoided, so that the installation period of the air duct is greatly shortened, and a large amount of cost is saved; and great potential safety hazards are avoided. In addition, due to the adoption of the air pipe flange mounting structure, the air pipe can be mounted in one step, repeated lifting in an inverted mounting method is avoided, the mounting quality of the air pipe flange is higher, and the air leakage at the air pipe flange is greatly reduced.
